Veris Industries H-921 Transducer

The Veris Industries H-921 Transducer, also referred to as the Hawkeye 921, is a high-performance split-core current transducer designed for precise AC current monitoring in commercial and industrial HVACR environments. This analog current sensor provides a loop-powered 4-20mA output proportional to the sensed current, making it ideal for load trending and motor status verification. Featuring three field-selectable ranges—0-30A, 0-60A, and 0-120A—this split-core current sensor allows technicians to adjust sensitivity via onboard slide switches without the need for jumpers or external calibration tools. The self-gripping iris design and removable mounting bracket enable rapid retrofit installation on existing conductors without disconnecting lines. Designed for building automation systems, the Veris H-921 is 100% solid-state, ensuring long-term reliability for fan and pump status monitoring. Its 2-wire configuration significantly reduces cabling requirements and commissioning time for contractors managing large-scale HVAC current sensing projects.

• Selectable Amperage Ranges: Field-adjustable settings for 0-30, 0-60, or 120 Amps provide high resolution and reduce the need for multiple SKUs.
• Simplified Wiring: Utilizing a loop-powered 2-wire 4-20mA signal reduces installation costs and simplifies integration with building controllers.
• Rapid Retrofit: The split-core housing clips directly over insulated conductors, eliminating the need to break the circuit or remove wires.
• Installation Flexibility: The included mounting bracket can be attached in three different configurations and is compatible with AH01 DIN rail clips.
• Reliable Performance: 100% solid-state construction with no moving parts prevents mechanical failure in demanding HVACR applications.

Is the H-921 compatible with 3-wire sensor setups?
The H-921 uses a 2-wire, loop-powered configuration. While it offers lower commissioning costs than traditional 3-wire sensors, ensure your controller's analog input is scaled for a 4-20mA loop-powered signal.

Can I use this on a variable frequency drive (VFD)?
This transducer is designed for 50/60 Hz sine wave applications. For monitoring the output side of a VFD where non-sinusoidal waveforms are present, performance may vary; it is best utilized on the line side of the drive for constant frequency monitoring.

What is the maximum voltage rating for the monitored conductor?
The device is rated for insulation classes up to 600VAC (UL) and 300VAC (CE). Always install the sensor on insulated conductors to ensure safe operation and compliance with local electrical codes.
